We look at the division of 80664 by 65 
We want to figure out the number of times 80664 can be divided by 65.

Step 1:
If we divide 8 by 65, we get 0 and a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Fetch the next digit (0) from the dividend, attach it to 8 and continue: 80 / 65

Moving on to step 2:
80 divided by 65 is 1 with a remainder of 15.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we take 65 away from 80, we end up with 15.
Take the next digit (6) from the dividend and append it to 15, then repeat: 156 / 65

Let's proceed to step 3:
The number 65 fits into 156 2 times, leaving a remainder of 26.
The number 2 becomes the next digit in our result. 
Result so far: 12.0
The remainder is 26 after subtracting 130 from 156.
Grab the next digit (6) from the dividend, add it to 26, then carry on: 266 / 65

Let's proceed to step 4:
The number 65 fits into 266 4 times, leaving a remainder of 6.
Put 4 as the next digit of the answer. 
Result so far: 124.0
Subtracting 260 from 266 leaves us with 6.
Fetch the next digit (4) from the dividend, attach it to 6 and continue: 64 / 65

Going ahead to step 5:
The number 65 fits into 64 0 times, leaving a remainder of 64.
The number 0 becomes the next digit in our result. 
Result so far: 1240.0
Subtract 0 from 64 to get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Step 6:
The number 65 fits into 640 9 times, leaving a remainder of 55.
The next digit of our result is 9. 
Result so far: 1240.9
If we take 585 away from 640, we end up with 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Advancing to step 7:
65 can be fit into 550 8 times, resulting in a remainder of 30.
Record the quotient 8 as the next digit in the result. 
Result so far: 1240.98
Subtract 520 from 550 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Going ahead to step 8:
The number 65 fits into 300 4 times, leaving a remainder of 40.
Use 4 as the next digit of our solution. 
Result so far: 1240.984
If we subtract 260 from 300, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 9:
When dividing 400 by 65, we get 6 with a remainder of 10.
The next digit of our result is 6. 
Result so far: 1240.9846
Deduct 390 from 400 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 10:
65 can be fit into 100 1 times, resulting in a remainder of 35.
Record the quotient 1 as the next digit in the result. 
Result so far: 1240.98461
Subtracting 65 from 100 leaves us with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Step 11:
The number 65 fits into 350 5 times, leaving a remainder of 25.
Write down 5 as next digit of the result. 
Result so far: 1240.984615
Deduct 325 from 350 and we're left with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Let's proceed to step 12:
250 divided by 65 is 3 with a remainder of 55.
The next digit of our result is 3. 
Result so far: 1240.9846153
Subtract 195 from 250 to get 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Let's proceed to step 13:
65 goes into 550 8 times with a remainder of 30.
The next digit of our result is 8. 
Result so far: 1240.98461538
If we subtract 520 from 550, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

After the division, we end up with 1240.98461538 and a remainder of 3e-08.
